Cooling vest to bring coolness to Chengdu Universiade volunteers, wearing "air conditioning" on the inner core | vest | Universiade
On July 16th, Chengdu, China Youth Daily reported that a special material vest caught the attention of reporters at a technology service station in Dayun Village, Chengdu. It is understood that this is a cold storage cooling vest specially designed by Chengdu Koripu Medical Equipment Co., Ltd. for the Universiade. A total of 100 items are brought for outdoor workers and volunteers in the Universiade.
The vest consists of an outer layer and an inner core, which can be disassembled. According to the introduction, the "inner core" is made of a new type of phase change material. It only needs to be frozen in the refrigerator for half an hour to bring two hours of coolness to volunteers outdoors at a high temperature of 35 degrees Celsius.
When the outdoor temperature is high, phase change materials will absorb the heat from the body surface and undergo a phase change process inside the vest, converting the heat into a cooling effect. At the same time, the vest will not produce condensation and will not wet clothes.
